+1 on the idea, -1000 on the name. It's neither atomic nor a
transaction. I believe that "critical section" is a more common term for
what you're proposing.
Probably the primitive could be placed in the thread or threading module,
so that it would be something like:
with threading.critical_section():
# ...
It might be nice to be able to escape out of the critical section using a
nested with: statement, as this would allow you to treat much of a program
as single-threaded, and then selectively allow task switching. But I'm not
sure what you'd call that API. :)
